IMPROVEMENT 1N SAW-Tanna.

To all whom 'it may concern l Be it known that I, W. B. NOYES, of Manchester, in the countyofHiIlsbol-ough, and State of New Hampshire, have invented certain new and useful Improvements in Saws; and I do hereby declare that the following is a full,-clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification, and in which- Figure l represents a perspective view of mysaw with the tooth-point removed, and v Figure 2, a perspective with the tooth-,point attached.

Similar letters indicate like parts in both figures.

The nature of my invention consists in the. employlnentof adovetailed point tothe teeth of saws, as and for the purpose hereinafter specified.

To enable others skilled in theI art to which my invention appertains, to make and usethe same, I will now describe its construction and operation.

In the accompanying'drawings- A represents a segment of a saw, the teeth of which are formed with their edges cut out, as seen inthe drawings. This saw can be'made of matelial.

11 representedJ steel point, which is cut so as to form a, dovetail with the saw-tooth, as seen in iig..2, and is provided with the key tl, which is driven into a mortise formed in to', the steel point near the dovetail, which firmly secures the point to the tooth of the saw.

By this a1'rangement,the steel points can be taken off, and ground upon a stone. Thereby the long and tedious operation of filing is avoided.

Having thus described lny invention,

lVhat I claim as new, and desire .to secure by Letters Patent, is

A saw provided with the steel dovetail point b, substantially in the manner and for the purpose described.

In testimony that I claim the foregoing as my own, I adir; my signature, in presence of two witnesses.
